Peakworks RK6-50 Roofers Kit — Universal Harness, 50 ft Lifeline, Rope Grab

A complete roofers kit with a rope grab — Peakworks RK6-50

The classic roofers kit puts a rope grab on the vertical lifeline, and the Peakworks RK6-50 is exactly that: a universal-fit full body harness, a 50 ft vertical lifeline, a rope grab that travels with you, and the roof bracket to anchor it — the whole ABC of fall arrest plus the anchor, boxed for one worker. The rope grab is the piece that keeps this the tight-clearance choice: it self-positions as you move, so arrest distance stays short.

Pros & cons

Specifications

What the RK6-50 is for

Occasional pitched-roof work — repairs, solar, gutters, inspections — where one worker needs the whole system and the rope grab’s tight clearance suits the roof. It sits in the fall protection kits collection, teaches the whole system through the fall protection equipment guide, and joins the jobsite loadout in the construction PPE checklist. Compare the field in the ranked kits guide.

Upgrading from the kit

When the universal harness no longer fits, the ranked harness guide covers sized options; the lifeline and rope grab have standalone upgrades in the vertical lifelines guide (the Guardian VL58 is a direct step up), and permanent roofs deserve a shingle-over anchor like the Guardian RIDG-1 or double-ring Ridge-It. Where clearance runs long, a self-retracting lifeline replaces the rope grab, and every kit needs trauma straps for the rescue plan.

How the RK6-50 compares

Peakworks’ own contractor kit swaps the rope grab for a 3 ft shock-absorbing lanyard; the Guardian 00815 and Werner K111201 are rope-grab brand alternatives. Prefer a permanent anchor left on the roof? Build around the anchor points collection, and pair the loadout with a hard hat and rated connectors. Everything lives in the fall protection collection.

Safety note: a kit supplies the components of a personal fall arrest system, but compliance lives in the install and the plan — fasten the roof bracket into sound structure per Peakworks’ instructions, run the clearance math for the 50 ft lifeline and rope grab, keep a prompt-rescue method ready per OSHA 1926.502(d)(20), and retire every loaded component after an arrest.

Ordering FAQ

Is the Peakworks RK6-50 Roofer’s Kit in stock and ready to ship?
This listing is active and ships through Amazon. Open the linked listing for live price, availability, and delivery speed.

What is in the Peakworks RK6-50 kit?
A universal-fit full body harness, a 50 ft vertical lifeline, a rope grab, and a roof bracket — the complete ABC chain plus the anchor bracket to make one worker compliant on a pitched roof, in one purchase.

How does the rope grab work in this kit?
The rope grab rides the 50 ft vertical lifeline and travels with you as you work down-slope, locking on the rope if you fall. It is the connector that keeps arrest distance short — unlike a fixed-length lanyard, it positions itself.

How is the RK6-50 different from the Peakworks contractor kit?
The connector: the RK6-50 uses a rope grab on the vertical lifeline, while the Peakworks contractor kit uses a 3 ft shock-absorbing lanyard. The rope grab needs less clearance and self-positions; the lanyard softens the arrest but needs more room.

What is the roof bracket for?
It is the kit’s anchor — a bracket that fastens to the roof structure to give the lifeline a rated tie-off point. Fasten it into rafters or trusses per Peakworks’ instructions, not sheathing alone.

Does the RK6-50 include everything one worker needs?
For a basic pitched-roof tie-off, yes: harness, bracket anchor, lifeline, and rope grab cover the ABC of fall arrest. You supply the fasteners into structure and a rescue plan — the kit is the arrest system, not the rescue.

Is the Peakworks kit OSHA compliant?
Installed and used per Peakworks’ instructions, the kit supplies the components OSHA 1926.502 requires — rated anchorage, harness, and connector. Compliance in use depends on correct bracket installation and the rescue plan you provide.

What size harness comes in the kit?
A universal-fit harness; check the linked listing for the exact fit range. Workers outside universal sizing should build a system around a sized harness instead.

What roofs is this kit for?
Pitched residential roofs where the bracket can fasten into wood framing. Standing-seam metal needs a seam clamp instead, and flat commercial roofs often use different systems.

Kit or separate components — which should I buy?
A kit is the fastest way to make one worker compliant and the best value for occasional roof work; the rope-grab format suits tighter clearance. Buy components when you want a better harness or many workers outfitted.

How do I inspect the kit before use?
Harness webbing and stitching, lifeline rope and rope grab function, the bracket and hardware for deformation or corrosion, and fasteners tight in sound structure. Anything questionable gets tagged out.

Does the kit include a rescue plan?
No — OSHA requires prompt-rescue capability wherever arrest systems are used, and that is on you: a ladder, lift, or rescue device plus trauma straps on the harness.

How do I reorder kits for a crew?
Reorder from this page — the listing and its linked Amazon ASIN stay constant, so equipping each additional roofer takes seconds.
